That bulb is a double ended one. It can not be put in an ellipsoidal reflector.

like this:

F2 - F1 distance is 130mm in my reflector. this lamp is 8-9cm total. put the light center at F1. it goes to additiional 45mm. it is far from the F2. just use a thin wire to connect to that end, like comercial lamps do.

I have asked. The ballast could convert to 100V-240V wide range by
replacing one of the IC chip. It costs additional ~$4. But the
manufacturer need 10 mininum order to make such change.

you can buy 300W transformer

or You can buy 4 units of 220 to 110 transformer- 70W
for about 12$ each (or less)

join them in parallel in a box and you will have 280W transformer !
(you can add one more for 350W)

After chatted with YWH. I think I would go ahead and start a group buy for this lamp / ballast, as long as I can geither other 9 people.

since adding $4 we can get 110V version. I would rather go that route.

It may be helpful to the groupbuy if someone with more experience can provide links to other items (e.g. reflectors, filters, etc) that can be used with this lamp.

let's see what YWH uses in his setup. I believe we can copy his design and get same items as his.

common setup would be put light center between a spherical reflector and a condensor. the same design is used in the most OHP's

The specs of the bulb list everything except the lumen output. Anybody know what it is?
